How do you "switch off" the last upgrade

more options

Along with the latest upgrade, you state "The headings in the message pane now show a "Correspondents" column by default instead of the "From" and "Recipient" columns. Existing folders will be upgraded to the new column, unless this upgrade is switched off" but you don't say how to switch off this upgrade. I'm not talking about auto-upgrade, just this one.

Chosen solution

Go to the bar at the top of the message list where it says Correspondents. At the right hand end of that bar is a drop-down menu from which you can choose which columns you want to see and in what order. You can replace Correspondents with From and/or Recipient if you wish. If you then right-click on the bar you can apply your chosen settings to other folders, or to a folder and all its sub-folders.
